Power Electronic Converters Simulation Model Verification for Grid Code Compliance Testing

Abstract

With increasing the diffusion of Power Electronic Converters (PEC) in modern and smart grid systems, the academic and industry R&D researchers rely more and more on the accurate and efficient modelling and simulation of PECs for both hardware and controller design. This paper focuses on the PEC simulation model verification for (time consuming and costly) grid code compliance tests. The simulation model developed based on a full-power laboratory test bench and the waveforms of fault ride through (FRT) tests were compared. The results show that the modelling approach based on averaged inverter captures the dynamic behavior with a good accuracy. Hence, the dynamic behavior of the inverter in FRT tests can be assessed using the simulation approach saving the time and cost required by full power testing.
